Tangential Question About TI-89

Sorry for being off-topic, but there's a startling lack of forums about calculator programming and I figured this would be a good place to check.

Can anybody tell me if a TI-89 function can be passed mathematical functions as an argument? For instance, I'm trying to write a series of programs that automate numerical methods like bisection method, Newton-Raphson, etc. I would really like to enter the analyzed functions from the command line as parameters instead of having to edit functions every time I start a new problem. The input I'm looking for would be something like this:

bisect(f,x,y,e)

Where
f= f(x)
x= beginning of interval
y= end of interval
e= prescribed error tolerance

I'd appreciate any help. Thanks in advance.
